This histogram visualizes the monthly total of dead and missing migrants, drawn as SVG rectangles within a React application. Each bin aggregates the sum of the "Total Dead and Missing" column from the Missing Migrants Dataset, using the d3.bin function to create monthly time buckets and d3.sum to accumulate values. The chart's axes use d3.scaleTime and d3.scaleLinear, with tick grids and labels styled via CSS. Hovering over a bar reveals its exact total through a tooltip.
